Name: __________________________________
the method of completing the square to transform any quadratic equation in x into
an equation of the form (x – p)2 = q that has the same solutions. Derive the
quadratic formula from this form. b. Solve quadratic equations by inspection (e.g.,
for x2 = 49), taking square roots, completing the square, the quadratic formula and
factoring, as appropriate to the initial form of the equation. Recognize when the
quadratic formula gives complex solutions and write them as a &plusmn; bi for real
numbers a and b
